Branching tubular structures are prevalent in many different organic and synthetic settings. From trees and vegetation in nature, to vascular structures throughout human and animal biology, these structures are always candidates for new methods of graphical and visual expression. We present a modeling tool for the creation and interactive modification of these structures. Parameters such as thickness and position of branching structures can be modified, while geometric constraints ensure that the resulting mesh will have an accurate anatomical structure by not having inconsistent geometry. We apply this method to the creation of accurate representations of the different types of retinal cells in the human eye. This method allows a user to quickly produce anatomically accurate structures with low polygon counts that are suitable for rendering at interactive rates on commodity computers and mobile devices.

用于解剖指导的分支结构的3D建模。

分支管状结构普遍存在于许多不同的有机和合成环境中。从自然界的树木和植被，到整个人类和动物生物学的血管结构，这些结构始终是图形和视觉表达新方法的候选对象。我们提供了用于创建和交互式修改这些结构的建模工具。可以修改诸如分支结构的厚度和位置之类的参数，而几何约束则可以通过不具有不一致的几何形状来确保生成的网格将具有准确的解剖结构。我们将这种方法应用于人眼中不同类型视网膜细胞的精确表示。
